We recently migrated all our mainframe data to a new Hitachi storage array
(9990v). In the initial setup we defined in HCD base (3390B) and alias
(3390A) volumes with wlmpav=yes (for the aliases). On the storage array we
have "Compatible PAV" enabled. In WLM we have Dynamic alias management
set to yes.
We are running z/os 1.4 and wlm in goal mode.
My problem is that I cannot see any dynamic assignment of alias volumes to
base volumes with high IOS queuing times. Using HDS Storage Navigator's
Compatible PAV manager I see the first 64 base volumes (out of 192) with 1
alias volume in each of my control units. I have yet to see anything
change over the past 4 weeks. I would have expected to see maybe a base
volume (beyond the first 64) to have an alias assigned especially if the
base volume has high ios queuing times (as seen in Omegamon).
I can however manually assign alias volumes to base but this is not dynamic
management. What am I missing to allow dynamic management of
pav's? Thank you.
